Could it be I don't care for Class A

You think that much.... hmmm. If that is the case it isn't class A that's the issue then. The amp doesn't get very warm to have class A bias.

Your levinson has a 4amp idle draw so it has some class A power .. Im estimating 25-high of 30 watts per channel class A bias ..

..That Purifi module is usually coupled to some sort of input buffer that provide a some extra gain. The point is that this buffer can color the sound to some extent. The buffer usually include an op amp but might used a discrete circuit to provide this gain..

The buffer is by design, this module will have OEM applications. It allows mfr to develop their own buffer stage (16 db) and power supply to give it their own signature sound. I would think a tube-based or fully discrete buffer module and linear instead of a switch mode PS would also contribute positively to the SQ. Im watching a few projects on the web that are underway using the Purifi modules and different buffers.

Going back to my Pass X250, I enjoyed that amp and the sound, however, moved to Levinson liking the sharper leading edges and quicker response better.

There are characters of the Coda 8 that are better than my Levinson, more intelligible vocals and better detail in some aspects overall, it's just as fast, yet there is something I still likeabout listening to the Levinson better. The Coda has such a quiet background you'd have to hear it to believe.

I am mad at myself it takes me so long to figure these things out, now I am not able to return the 8. I'm going to try to get $5k back out of it, not even 120 days yet.

The real mystery to me is what is it I can't fully enjoy the 8, it's a great amp by anyone's standards. The 8 version I have is Class A for the first 12 watts, I'm wondering if I have an issue that I am one who may not prfer Class A. I don't like overly aggressive amps either. I guess we all have our sweet spot.

I also listen to a wide variety of music so amps that may excel on certain genres would present an issue for me.

The correct answer is No. But that is only because none of the amps you've listed are class A. If they are class A, its to full power, not 12 watts or anything like that. IOW you're describing AB amps that you don't like as opposed to other AB amps that you do. Some are biased more heavily than others but that is very different from actually being class A. For fun maybe see if you can borrow a real class A amp and see if you still feel that way.

FWIW though the differences we hear in amps usually are not about the class of operation. Its about the distortion they do or do not make.
